Patent number: 11904328Abstract: A method of separating a fluid includes adding a fluid to a canister of a fluid separator. The canister includes first and second barriers disposed concentrically within the canister that define a first and second annulus within the canister, and a canister rotor having a first magnet associated therewith. The method includes rotating an induction base rotor disposed within an induction base. The induction base rotor includes a second magnet. The canister rotor and the induction base rotor are magnetically coupled and rotating the induction base rotor causes the canister rotor to rotate. The method further includes forming a vortex in the fluid via the rotation of the canister rotor, and the vortex causes the fluid to separate into a first component and a second component.Type: GrantFiled: August 30, 2022Date of Patent: February 20, 2024Assignee: SpineSmith Partners, L.P.Inventors: Richard J.

Patent number: 10034764Abstract: A method and apparatus is provided for use in spinal fusion procedures. An interbody fusion device has a first piece that is a load bearing device designed to bear the axial loading from the end plates of adjacent vertebrae. A second piece of the interbody fusion device is a retention device whose function is to prevent migration of the load bearing device. One or more fasteners secure the retention device to the vertebrae above and below the load bearing device. The fasteners cause the end plates of the vertebrae to compress the end plates to the load bearing device to facilitate proper fusion. The second piece can be configured to include lips that abut the apothyseal rings during, with the plate including bores angled such that fasteners penetrate the apothyseal rings.Type: GrantFiled: April 27, 2012Date of Patent: July 31, 2018Assignee: SpineSmith Partners, L.P.Inventors: Richard Kana, Kevin Dunworth, Luis Duarte, Brian Burkinshaw, Mukund Gundanna, Ryan Medema
